OIL-WELL. RIG.

Specification of Letters Patent.

Patented March .20, 1906.

Application filed May 9, 1905; Serial No. 259,583. I

To all whom it mag concern:

Be it known that we, LEWIS H. EMERSON and SAMUEL P. KERsTETTER, citizens of the United States, residing at De Young, in the county of Elk and State of Pennsylvania,

' have invented a new and useful Oil-Well Rig,

. rigs employed in connection with mechanismof the following is a specification. This invention relates more particularly to for sinking oil or other deep wells; and the prmclpal object is toprovide a novel structure wherein a comparatively small amountcross-sectional viewon the line 4 4 of Fig. 3.

Fig. 5 isa cross-sectional view through the nose-sill, showing'the connection of the brace therewith. i

Similar reference-numerals designate corresponding parts in all'the figures of the drawings.

Inthe embodiment illustrated a pair of spaced mudsills 3 and 4 is employed, upon one of which is mounted a samson-post 5, the

lower end of which is dovetailed; as shown at 6, in the central portion of the mudsill and is retained in place by a suitable wedge 7.

- and projecting from one side of the sameis a Upon the upper end of the Samson-post are secured the usual bearings 8, in which isjournaled a walking-beam 9. Secured trans versely to the Samson-post between its ends cross-bar 10, and suitably fastened upon this cross-bar are spaced downwardly-lnclined girders 11, the lower ends of which are rigidlysecured to the mudsill 4. Braces 12 are fastened to intermediate portions of the girders, one of the braces being" attached, as shown at 13, to the lower'end of the Samson-post, the other being engaged with the mudsill 3 at one side of said Samson-post. As shown, this engagement is secured by means of a seat 14,

cut into the upper side of the mudsill and having a longitudinally-disposed abutmentflange 15.at its rear side. The lower end of the brace 12 engagesv in the seat 14, and between said lowerend and the flange 15 is awedge 16. The brace is introduced to the seat and in'advance of the flange through an entrance-mouth 17, located at one end of said flange 15.

Disposed on the opposite side of the mud- $111 to the mudsi114is a. nose-sill 1s, and extending from this nose-sill are inclined braces 19, one of which is suitably fastened to the samson-post, the other being secured to the free end of the cross-bar 10 and constituting a support therefor. The lower ends of the braces 19 are attached to the nose-sill in the same manner that the brace 12 is con-. nected to the sill 3-that' is to say, the nosesill18 is provided in its upper side with seats 20, the rear walls of which are formed by up-' standing flanges'21, constituting abutments. The lower: ends of the braces 19 are located in the seats and are borne against by wedges 22, which also bear against .the flanges 21. Entrance-mouths 23 for permitting the introduction of the braces to the seats extend from the rear side of the nose-sill. The samsonpost is furthermore strengthenedv by a transversely-disposed brace 24, the lower end of which is attached to one end of the mudsill 3, the upper end being secured directly to said Samson-post.

. J ournaled in boxes 25, secured to the girders 11, is a band or drivewheel 26, the shaft thereof carrying a crank'27 at one end, which crank is connected, by means of a pitman 28, with one end of the walking beam. 'The girder 1 1, that is adjacent to the crank, is pref-' erably strengthened by a strut-brace 11 Driven from the band or drive wheel is a sand-reel 29, one end of which is journaled in a jack-post 30, mounted on a stringer 31, that connects. the ends of the mudsills 3 and 4. -The jack-post is braced, as shown at 32. The. other end ofth'e sand-reel is journaled in a lever 33, pivoted, as shown at 34, to one of the girders-11, the upper end of said lever having attached thereto an actuating-bar 35.

Ioo

A friction-wheel 36, carried by the sand-reel,

coacts in the usual manner with the drive or band wheel.

This structure is employed in the ordinary manner 'well known to those skilled in the art.

Particular attention is invited to the comparatively small amount of timber used in the construction. Thus the subsills, main sills, and two mudsills of the ordinary rig now in common use, as well as the jack-posts, are dispensed with. At the same time the structure is strong and durable, powerfully braced, and has proven by actual experience to be entirely practicable and eflicient in op eration.

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described invention will be apparent to those skilled in the art with out further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to Without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus described our invention,what we claim as new, and desire to secure by Letters Patent, is

1. In a well rig, the combination with spaced mudsills, of a Samson-post mounted on one of the sills, a walking-beam located on the post, a girder connecting the post and the other sill, a drive -wheel 1ournaled on the girder, and a brace connecting the lower end of the Samson-post and the portion of the girder adjacent to the drive-wheel.

2. In a well rig, the combination with spaced mudsills, of a Samson-post mounted on one of the sills, a walking-beam pivotally supported on the samson-post, spaced downwardly-inclined girders having a connection with the post between its ends, a band-wheel journaled to and between the girders, and downwardly-inclined braces connected respectively to the intermediate portions of the girders, one of said braces being connected to the sill that carries the Samson-post.

3. In a well-rig, the combination with a base-frame, of a samson-post mounted thereon, a walking-beam mounted on the upper end of the samson-post, a cross-bar secured to the post below the mounting for the walking-beam, downwardly-inclined girders secured to the cross-bar and the base-frame, and a drive-wheel ournaled on the girders and connected to the walking-beam.

4. In a well rig, the combination with spaced mudsills, of a Samson-post mounted on one of the mudsills, a cross-bar secured to the post, downwardly-inclined girders connected to the cross-bar and to the other mudsill, braces between the girders, the post, and the sill therefor, and a drive-wheel journaled on the girders.

5. In a well -rig, the combination with spaced mudsills, of a nose-sill spaced there from, a Samson-post mounted on one of the mudsills, a cross-bar secured to the samsonpost, girders connecting the cross-bar and the other mudsill, a drive-wheel journaled on the girders, and braces between the nose-sill, the cross-bar, and the Samson-post.

6. In a wellrig, the combination with spaced mudsills, of a stringer connecting the same, a Samson-post mounted on one of the mudsills, girders having a connection with the samson-post and also connected to the other mudsill, a drive-wheel journaled on the girders, a jack-post mounted on the stringer, a lever ournaled on one of the girders and a sand-reel journaled at one end in the jackpost and at its other end in the lever, said reel being movable into and out of coaction with the drive-wheel.

7. In a well rig, the combination with spaced mudsills, of a nose-sill located at one side of the same, a Samson-post mounted on the mudsill that is adjacent to the nose-sill, a cross-bar secured to the Samson-post, downwardly-inclined girders secured to the crossbar and to the other mudsill, braces for the girders, braces for the crossbar and samsonpost connected to the nose-sill, a drive-wheel journaled onthe girders, a walking-beam pivoted on the samson-post, a connection between the driving-wheel and walking-beam, a stringer connecting the mudsills, a ack-post mounted on the stringer, a lever pivotally supported on one of the girders, means for actuating the lever, and a sand-reel journaled in the lever and in the jack-post and movable into and out of coaction with the drive-wheel. In testimony that we claim the foregoing as our own we have hereto afiixed our signatures in the presence of two witnesses.
